Extruding forming mold for polymer

The invention relates to an extruding forming mold for a polymer. The mold comprises an extruding mold and a foam adjusting fuse mold head connected with the extruding mold, and the center of the extruding mold is provided with a plurality of capillary extruding holes; the foam adjusting fuse mold head comprises a wire-drawing mold head and a foam adjusting fuse-type cavity, the foam adjusting fuse type-cavity is divided into three sections, the first section is an inlet pipeline, the section is a transition zone, the third section comprises a convergence area and a steady-flow zone, and the convergence zone is located between the transition zone and the steady-flow zone; the height of the inlet pipeline is same with that of the transition zone, the height of the convergence zone is gradually reduced in the flowing direction of fusant, the height of the steady-flow zone is kept constant, the width of the inlet pipeline and the steady-flow zone is kept constant, the width of the transition zone and the converg
